The Watchtower Society’s requirement that Jehovah’s Witnesses must refuse to accept blood transfusions dates back to 1945. Misinterpreting the Old Testament prohibition against eating animal blood as a routine food item, the Watchtower Society began teaching that receiving a blood transfusion was “eating human blood”. The Watchtower teaches Jehovah’s Witnesses to believe that receiving an infusion of human blood into their body’s circulatory system is the exact same thing as eating or ingesting blood into their body’s digestive system. Please notice the following statements.
The Watchtower, July 1, 1951 p-414 said, “A patient in the hospital maybe fed through the mouth, through the nose, or through the veins. When sugar solutions are given intravenously it is called intravenous feeding. So the hospital’s own terminology recognizes as feeding the process of putting nutrition into one’s system via the veins. Hence the attendant administering the transfusion is feeding the patient through the veins, and the patient receiving it is eating through his veins.”
